OK, so I got some yellow 230's from RheemaDura screen which are awesome.
But previously, I was using white 120's (?) which dried and exposed just fine after about 20 minutes with a fan on them after coating.
A couple of days ago I coated and exposed the 230's in the same manner that I would have the other screens. When I sprayed out the image, my emulsion (Which is Ulano- I know... I know...) started slithering around and some of it fell off completely.
MY QUESTION IS THIS: Doesn't this sound like it has more to do with emulsion dry-time, rather than exposure? Because the exposure worked just fine before. Perfectly before. The only difference is that the mesh is more dense, and therefore would need more dry-time, right?
MY OTHER QUESTION IS THIS: How long should it take to completely dry before I can expose?
